We all like to know the temperature, right? Well, with the SparkFun TMP102 Digital Temperature Sensor, we've made it just about as easy as it gets. Based on the original Digital Temperature Sensor Breakout - TMP102, we've added Qwiic connectors to bring this board into our plug-and-play Qwiic Ecosystem and added an address jumper instead of breaking out the address pin. However, Sparkfun still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

The TMP102 itself is an easy-to-use digital temperature sensor from Texas Instruments. While some temperature sensors use an analog voltage to represent the temperature, the TMP102 uses the I²C bus of the Arduino to communicate the temperature.

The TMP102 is capable of reading temperatures to a resolution of 0.0625°C, and is accurate up to 0.5°C. The breakout has built-in 4.7kO pull-up resistors for I²C communications and runs from 1.4V to 3.6V. I²C communication uses an open drain signaling, so there is no need to use level shifting.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.
